I think there are a few threads, some more comprehensive than others, I've added to more than one I think as I've done all mine (though the numberplate ones have reverted to normal at present).

In my experience the worst bulb by far is the D2 glovebox, the only sensible method is to take the glovebox out (quite quick & easy to do) as otherwise you WILL break the holder. :tuttut:

There should be one or two done by me already.
I've converted the every bulb in my car with LEDs.

Currently working on side lights and DRLs when I get time.
